Ox Alpha likely GLM-5.3: the mystery model's fingerprint

www.orcarouter.aiPublisher’s summary
Ox Alpha's full DeepSWE run lands ~63%, on par with GPT-5.6 Sol mid. Fingerprinting still points to Zhipu's GLM-5.3 Flash — and it's free for one week.
Independent fingerprinting now points to the anonymous frontier model being Zhipu AI's GLM-5.3 — presumably the Flash variant, as analysts have widely reported — and the identification is forensic rather than an announcement.
